Abstract
A method of fabricating a semiconductor device in which a plurality of conductive lines having a fine pitch and a uniform thickness can be formed is provided. The method includes forming a plurality of first conductive patterns in a insulation layer as closed curves, forming a plurality of mask patterns on the insulation layer, the mask patterns exposing end portions of each of the first conductive patterns, and forming a plurality of second conductive patterns in the insulation layer as lines by removing the end portions of each of the first conductive patterns.
